1 Claim.

This invention aimsto provide a simple but efiicient machine, adaptedfor grinding toasted bread, crackers, nuts and the like, eitherdomestically or commercially, for producing meal: although the machi-nemay be employed in connection with any substance which can be operatedupon by it.

The invention aims to provide novel means for feeding the material whichis to be divided, to provide rotary dividers of novel form, and tosupply novel means for actuating the dividers. A further object of theinvention is to provide, in a device of the class described, a simplebut effective means where-by coarse and fine material, delivered by themachine, may be segregated.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the presentinvention appertains.

With the above and other objects in view,

which will appear as the description proceeds, the invention resides inthe combination and arrangement of parts and in the details ofconstruction hereinafter described and claimed, it

being understood that changes in the precise embodiment of the inventionherein disclosed, may be made within the scope of what is claimed,without departing from the spirit of the invention.

In the accompanying drawings:

Fig. 1 shows, in vertical section, a device constructed in accordancewith the invention, parts remaining in elevation;

Fig. 2 is a front elevation of the device depicted in Fig. 1;

Fig. 3 is a vertical section on the line 33 of Fig. 1;

Fig. 4 is a horizontal section on the line 4-4 of Fig. 1;

Fig. 5 is a longitudinal section showing a modified divider.

In carrying out the invention, there is provided a support I, in theform of a standard, equipped at its lower end with a table clamp 2, thesupport carrying a horizontal, cylindrical barrel 3, closed at its rearend, as shown at 4, the barrel being provided at its rear end with anupstanding neck or receiver 5.

A feeder block 6 is movable vertically in the receiver 5. A lid I isattached to the feeder block 6 and forms part thereof. The edge of thelid I forms a flange 8, which, cooperating with the upper end of thereceiver 5, limits the downward movement of the feeder block 6. The lidI carries a handle 9, of any desired construction. In

the lower end of the feeder block 3 there is a concaved recess I3,struck on an arc, the center of which is coincided with the axis of ashaft II adapted to carry dividing instrumentalities hereinafterreferred to.

A bearing member I4, in the form of a bar, is located at the forward endof the barrel 3 and abuts thereagainst, the bearing bar being providedat its ends with rearwardly extended fingers I5, carrying holding means,such as set screws I6, adapted to engage the barrel 3 and to hold thebearing member I4 in place removably.

The bearing member I4 is supplied intermediate its ends with an openingI! wherein is received a reduced tip I8 on the forward end of the shaftI I, hereinbefore mentioned.

The shaft I I is supported for rotation, not only in the bearing memberI4, but in the rear end wall 4 of the barrel 3. At its rear end, theshaft I I is supplied with a polygonal foot I9, on which is fitted thesocket 20 of a hand crank 2|. A screw 22 in the rear end of the socket20, engages the end of the shaft II, and holds the crank 2| in place.

A cylindrical divider 23 is located in the barrel 3 and may be ofvarious constructions. As shown in Fig. 4, knives 24 are struckoutwardly from the body of the divider, to define openings 25. Theknives 24 move in close relation to the inner surface of the barrel 3,and there is a space between the outer surface of the divider and theinner surface of the barrel, the space being designated by the numeral26. The divider 23 has a rear end wall 21, abutting against the rear endwall 4 of the barrel 3, the shaft II being secured in the rear end wall21. A cruciform bracket 28 is secured to the shaft I I, about midwaybetween the ends thereof, the outer ends of the arms of the bracketengaging the divider 23, to strengthen its mounting on the shaft I I. Inconnection with some forms of dividers, the bracket 28 may be omitted.

The material to be divided is placed in the receiver 5, within theconcaved recess II] at the lower end of the feed block 6, and the feedblock is thrust down. In this way, the material to be divided is kept inclose and intimate contact with the divider 23. When the material in thereceiver 5 has been used up, the flange 8 of the feeder block 6 comesinto contact with the upper end of the receiver 5, and the lower end ofthe feeder block does not come into contact with the divider.

The material which is being divided moves forwardly. Some portions ofthe divided material will be in the space shown at 26 in Fig. 1, andsome portions of the material will be located inside th divider 23. Thefiner material passes through the openings 25 of Fig. 4, into thedivider 23, and this finer material is discharged at the forward end ofthe machine, through the open, forward end of the divider. The coarsermaterial remains in the space 26, and is segregated from the finermaterial, because the barrel 3 is provided near its discharge end with adepending spout 29, shown in Fig. l, the coarser material passingdownwardly through the spout.

In Fig. 5, parts hereinbefore described have been designated by numeralsalready used, with the sufiix a. The divider 23a replaces the divider 23when meal is to be turned out. The parts 24a, instead of being knives,as shown in Fig. 4, are outstanding burrs, adapted for the specificpurpose in view.

Although the machine has been shown as being operated through theinstrumentality of a hand crank 2 I, no illustration is required tosupport the statement that the shaft may be power operated if desired.

The machine hereinbefore described is simple in construction, but itwill be found thoroughly advantageous for the ends in View, and capableof consummating the objects set forth in the opening portion of thisspecification.

Having thus described the invention, what is claimed is:

In a food grinder, a support, a substantially horizontal cylindricalbarrel carried by the support and open at its forward end, the barrelhaving a rear end wall and being provided with an upstanding receiverhaving a rear wall in vertical alignment with the rear end wall of thebarrel, a depending spout carried by the barrel and communicating withthe barrel, and a cylindrical tubular divider supported coaxially in thebarrel,

for rotation therein, and extended forwardly above the spout, to a placeclosely adjacent to the open end of the barrel, there being a space forcoarsely divided material between the divider and the barrel, thedivider having an open forward end, and having openings definingdividing ele ments distributed throughout the entire length of thedivider and extended outwardly into close relation to the barrel; thespout being of small cross section and being disposed close to theforward end of the barrel and the barrel and the divider being extendedwell beyond the forward wall of the receiver whereby the dividingelements will have opportunity to work on coarsely divided materialbefore it reaches the spout.
